A process for the preparation of prostaglandin compounds of formula I, wherein A is a group selected from the group consisting of C.sub.1. an alkyl group; C.sub.7.n.-C.sub.16.n. an aralkyl group in which the aryl group is optionally substituted with one to three substituents selected from the group consisting of C.sub.1. an alkyl group, a halogen atom and a CF3 group; and a group (CH.sub.2.n.), sub.n.n.OR ', where n is a number from 1 to 3 and R' represents C.sub.6.n.-C.sub.10.n. an aryl group which is optionally substituted with one to three substituents selected from the group consisting of C.sub.1. an alkyl group, a halogen atom and a CF3 group; B is a group selected from the group consisting of OR´´ and NHR´´, where R´´ represents C.sub.1.n.-C.sub.6.n. an alkyl group; and ----- represents a double bond or a single bond. Also disclosed are novel intermediates resulting from this process. |
